A little while back my girlfriend jumpstarted a co-workers car that had a dead battery. Unfortunately, neither of them knew exactly what they were doing it seems as though something occurred during that mishap. Since this event she has had something draining the battery on her car...a slow drain that after 3 days will leave the battery dead. We know the alternator is working because when she drives her car daily there are no issues (so it does charge it during drive). She brought it to the Volvo dealer (one I have very little faith in) and they couldn’t find any issues after doing some diangonosing. I performed a parasitic draw test this morning and it looks as though something is draining 750 mili-amps. I went through all mini fuses in the passenger footwell and under the hood and pulled them one by one...no luck. I read through a few threads, but none seemed to offer advise if I didn’t find what was draining the system on the draw test. Any help would be greatly appreciated!

Doesnt newer cars have 2 fuse boxes?One of them have to have the fuse you are looking for.

 

I checked both under the hood and the dash fuse boxes. No luck...

 

Try to pull some relays too.
